DoxyPEP (taking a 200mg dose of doxycycline within 72 hours of condomless sex) is highly effective at preventing syphilis and chlamydia. France led the major clinical trial proving DoxyPEP's efficacy (the ANRS DOXYVAC trial). Because of this, the French medical establishment is open to DoxyPEP.

Availability in the French System

In France, DoxyPEP is not officially authorized as a blanket preventative measure for the general public, but major infectious disease societies (like SPILF) have issued guidelines allowing doctors to prescribe it on a case-by-case basis.

You are highly likely to be prescribed DoxyPEP if you meet the clinical profile:

  • You are a man who has sex with men (MSM) or a trans person.
  • You have had multiple recent bacterial STIs (especially syphilis).
  • You are already engaged in a PrEP program.

How and Where to Get It

Because DoxyPEP requires specialized knowledge, skip standard general practitioners (médecins généralistes). They likely will not know the protocol.

Where to go:

  • Your PrEP Provider: Ask the infectious disease doctor managing your PrEP during a routine check-up.
  • A CeGIDD: These free sexual health clinics are the best route if you are not yet in the system. CeGIDDs can prescribe DoxyPEP; some dispense the doxycycline on-site for free, while others give you a prescription to fill at a pharmacy — call ahead to check which applies at your local centre.

What to say:

  • "I would like a prescription for DoxyPEP." -> "Je voudrais une ordonnance pour la DoxyPEP."
  • "I have had recent bacterial STIs." -> "J'ai eu des IST bactériennes récemment."

Cost and Dispensing: If prescribed by a doctor, the cost of doxycycline is heavily reimbursed by the state/Carte Vitale system. It is a very cheap generic antibiotic. Even paying the full price without a Carte Vitale, a box is only a few euros — doxycycline is one of the cheapest generics on the market.

If you are sourcing doxycycline through other means (e.g., repurposing an acne prescription), you must understand the math. Acne is usually treated with 50mg or 100mg daily. DoxyPEP requires a 200mg dose within 72 hours of sex. Taking a smaller dose will not protect you from syphilis and actively contributes to antibiotic resistance.
